O'Reilly: Perl Program Repair Shop and Red Flags “Most years, I have to slave over new tutorials. But this one almost wrote itself once I found the right examples. I'd start with someone's 71-line Perl program, and go over it line by line. Each time I came to a line that was unnecessary, I'd take it out and write a slide about it. The result? 39 slides and a 32-line program.” [QubeQuorner]
